You can use the ReactGridLayout custom element in templates which allows you to cleanly specify how many rows and columns you'd like. It also supports props for columns, rows, responsive breakpoints, and layout change events.
Although the author states it has fewer features than Packery or Gridster, it supports some cool stuff like vertical auto-packing and dragging and resizing.
Angular Debug Bar and Reading Position Indicator
Maciej Rzepiński sent in two useful Angular projects:
angular-debug-bar allows you to including a new element, angular-debug-bar, to show some statistics about the current page. This includes a count of $watch and $listener items, DOM objects, and page load time. Each metric is defined with a registerPlugin method, so you might be able to add new metrics although I haven't tried that myself.
angular-rpi is based on the Reading Position Indicator post from CSS-Tricks. It shows a bar at the top of the page as you scroll the document:
You can use it with the rpi directive. Both projects have a demo that you can run locally. If you want to edit the progress bar styles, then you can use the .scss file and run npm install ; bower install ; gulp.
This plugin comes from the "should I just use a table?" department of design technicalities that we still have to deal with in 2012: equalize.js (GitHub: tsvensen / equalize.js, License: MIT/GPL). Created by Tim Svensen, this plugin resizes elements to match their height or any other dimension supported by jQuery Dimensions.
It works by calling a single method on the parent selector:
// Height is the default

jQuery Builder (GitHub: jgallen23 / jquery-builder, License: MIT, npm: jquery-builder) by Greg Allen is a web-based tool for building a custom version of jQuery 1.8.1. As jQuery has evolved it's got a lot easier to include only the components necessary for a given project. This particular solution has been made using Node, and is installable with npm.
Gridster.js (GitHub: ducksboard / gridster.js, License: MIT) from Ducksboard is a grid plugin that allows layouts to be designed by drag and drop. Elements can span multiple columns, and by dynamically added and removed. Any element can be used because Gridster is based around data attributes.
Gridster is distributed with suitable CSS, and supports IE 9+, Firefox, Chrome, Safari, and Opera.
